The current standard for stairs in the US is a maximum of 7" per riser.
10' is 120", divided by 7" is just over 17,
but since the maximum allowable is 7" you're going to have to have 18 risers at 6 2/3"
Don't panic, your framing square has one leg divided into 12ths,
8/12 = 2/3

If the roof pitch is 10 12 with a 10' run what will be my rise?
A 10/12 means for every foot of run your rise is 10". so, 10' x 10" = 100" rise in 10 feet.
Roof 50 foot by 100 foot with a 412 pitch what is the formula?
a 100 foot run with a 50 foot rise would give you a 6/12 pitch
What is the maximums for the unit rise and unit run in the building code for stairs?
The total of the rise plus run does not exceed 18" -
How many inches does the Stair tread depth typically stick out more than the run?
there are no set inches .... stairs are cut to a RATIO of the amount of space you need to climb [ say to the second floor of a house or to the top of a deck ] the steeper you make the stairs the higher this ratio will be. 10 inches of tread - and 8 inches of rise - is a common ballpark figure ... you cannot just decide i want my steps to be ______ height. you much use math and figure out how many steps can be divided equally into the total height. local building codes sometimes set a minimum and maximum height to the individual risers. making steps with one odd sized riser [ say shorter or higher than all the rest of the stairs so that it comes out correctly- and usually on the bottom step ] is a HUGE no-no as well. things too look up on the web are "framing square" and "stair stringer"
How much rise in a 7 degree roof over 1 meter?
7 degrees is 1 1/2" rise in one foot.
What is rise of stair?
The rise of a stair is the vertical distance between the treads. The term can be used for the height of the full set of stairs. A riser is the vertical board running along the front of the step.
What is the maximum stair rise and minimum tread for industrial stairs?
Normally 7" rise and 11" run.
What is the normal rise of stair treads?
code is no more then 7.5 inches
How do stairs represent slope?
I would say that they have a rise over run (just like slope). So say that a stair goes up 2 feet every stair across, it's slope would be 2/1 or 2 (but i could be totally wrong).
How do you use a framing square to lay out a stair?
You use the two scale's,leg's, of the square to layout the rise and run of your stair's. Rise = the height of each step example 7.5". Run = the length of each step example 12".
The stair tread depth is typically- more than the run so that it sticks out nose?
Nosing is not taken into account when calculating initial stair set-out, but added later. The rise of a residential stair in the US is 8" and the run is 10" with a nose of 1". This means that the tread depth is 10", the height from stair to stair is 8" and the tread sticks out 1" over the the tread below. It is still 10" from front to back. A commercial stair is 7" rise, 11" run, 1" nose.
What is the difference between stair tread and stair riser?
The tread is what you step on, the riser is the part going up. Rise=riserThe tread is what you step on. The riser is the upright piece your toe hits.
What is the stair construction code in Massachusetts?
there is plenty of information on actual stair const., but not a lot of info. about the pad the stairs start from. Standards say concrete slab 4'' thick . Can this slab be taller or thicker to change stairway rise and run ?
What are legal dimensions of a stair step?
The most comfortable dimension of a stair step I have found is a 7 1/4" rise with a 10 1/2" tread. The rise should be no greater than 8" and the tread should be no less than 10". For new construction, contact your local code enforcement officer for more information on codes in your area.
What is the slope of a ramp that has a rise of 1 inch over a run of 10ft?
Slope is equal to rise over run. There are 12 inches in a foot, so 10 feet is actually 120 inches. Therefore, the slope is equal to 1/120.
Why does it seem that there are always an uneven number of steps on a stair case?
The rise of a step should be around 7". When computing the number of rise units, a carpenter will divide the total rise by the number 7. This will give a starting point in determining the number of individual step risers.
The stair tread depth is typically how many inches more than the run so that it sticks out?
Your run should always be longer than the rise. Current International Residential Code states the rise cannot be greater than 7-3/4" and the run cannot be less than 10". A common stair stringer has a 7" rise with a 11" run. rip your stair tread to 12" , this will over hang the run on the stringer by 1", when you install your toe kicks, use 3/4" material and you will wind up with a 1/4" overhang on each tread. Of course there are different ways to do this, but I believe this is most common.
